Given numbers are 980, 625, 628, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 625) = 122500
GCD(980, 625) = ( 980 x 625 ) / 122500
= 980 / 625
= 980
Step2:
LCM(5, 628) = 3140
GCD(5, 628) = ( 5 x 628 ) / 3140
= 5 / 628
= 5
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 980, 625, 628, 140 is 1
